You're not missing anything. It's a cautionary step only. If you are about to do something with the machine and remerging the whole universe would be inconvenient at this moment in time, or you may want to reconsider/change some of your settings, then --pretend will give you this chance. I've made the habit of using it almost without thinking, but you can of course not use it, or substitute it with -a. -- Regards, Mick
